Problems solved by technology

This structure is a relatively mature technology and has been widely used in the field of electric shavers. The application of this driving technology is low in cost and easy to implement. However, this driving technology needs to extend the drive shaft outside the body and drive The shaft protrudes from the outside of the housing to realize the transmission fit, so there will be a sealing problem. If the seal is not good, when the shaver is rinsed with water, the water will enter the inside of the machine and cause damage to the machine; in addition, the drive shaft and the transmission shaft are matched. When the machine is in use, it will produce greater vibration and noise; third, when there are long and many beards entering the knife net for cutting by the moving knife unit, it is easy to overload the machine and cause the machine to be stuck. It may even cause the cooperation between the drive shaft and the drive shaft to fail; fourth, how to form a magnetic field to make the magnetic drive reliable, improve the transmission accuracy, and reduce the power loss is a problem to be solved in the actual product

Embodiment 1

[0036] like Figures 1 to 3 As shown, a magnetically driven electric shaver includes a main body assembly 1 and a cutter head assembly 2, and the cutter head assembly 2 is arranged on the main body assembly 1. Unit 102, a battery that provides power for the drive unit 102, the battery is located in the body 101, a USB charging port for charging the battery, the cutter head assembly 2 includes a moving knife unit 203 and a shell for supporting the moving knife unit 203 Body 201, a knife net arranged outside the moving knife unit 203, the knife net is used to cooperate with the moving knife unit 203 to shave beards, the drive unit 102 includes a motor 1021, wherein the drive unit 102 also includes a The active magnet 103 inside and the driven magnet 204 arranged in the housing 201 , the movable knife unit 203 is driven to rotate under the action of the motor 1021 , the active magnet 103 and the driven magnet 204 . There is a transmission module between the driven magnet 204 and...

Embodiment 2

[0056] The difference between embodiment one and embodiment two is that, as Figure 7 , Figure 8 As shown, the upper end of the body 101 is provided with a second boss, and the second boss at least partially extends into the connecting neck 202. The advantage is that the reliability of the transmission is ensured, so that the head assembly 2 of the shaver is in operation. Do not shift.

[0057] The connection between the second boss and the connecting neck 202 is through an anti-rotation structure, which prevents the cutter head assembly 2 from shifting during the working process and makes the transmission invalid. The anti-rotation structure may be a turn-lock fit between the second boss and the connecting neck 202; or, the outer wall of the second boss is provided with a first groove, and the inner wall of the connecting neck 202 is provided with a first groove. The groove fits the first protrusion, and the first protrusion extends toward the center line of the cutter hea...

Abstract

The invention relates to the field of domestic appliance, in particular to a magnet drive electric shaver. The magnet drive electric shaver solves the problem of waterproof sealing difficulty and thetransmission structure without overload protection function in an electric shaver with a current transmission structure. The magnet drive electric shaver comprises a main body assembly and a cutter head assembly; the cutter head assembly is arranged on the main body assembly; the main body assembly comprises a main body and a driving unit arranged in the main body; the cutter head assembly comprises a movable cutter unit and a shell used for supporting the movable cutting tool unit; the driving unit comprises a motor, a driving magnetic body arranged in the main body and a driven magnetic bodyarranged in the shell; the driving magnetic body and the driven magnetic body are arranged to be multipole magnetization magnetic bodies; and the movable cutting tool unit is driven to rotate by themotor, the driving magnetic body and the driven magnetic body. Excellent waterproofing effect is achieved and overloading protection is achieved by magnet drive.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a magnetically driven electric shaver. Background technique [0002] An electric shaver generally includes a main body assembly and a cutter head assembly connected to the main body assembly. The main body assembly generally includes a body, a drive unit, a battery, and a charging port. The cutter head assembly generally includes a knife net, a moving knife unit, a housing, and a transmission shaft, etc. , the drive unit includes a motor, a gear unit, and a drive shaft, and drives the movable knife unit to rotate through the joint action of the motor, gear unit, drive shaft, and transmission shaft. This structure is a relatively mature technology and has been widely used in the field of electric shavers. The application of this driving technology is low in cost and easy to implement. However, this driving technology needs to extend the drive shaft outside the body and drive T...
